  2. Potential applications of graphene - Wikipedia

    en.wikipedia.org/wiki/Potential_applications_of...

    Graphene solar cells use graphene's unique combination of high electrical conductivity and optical transparency. [103] This material absorbs only 2.6% of green light and 2.3% of red light. [104] Graphene can be assembled into a film electrode with low roughness. These films must be made thicker than one atomic layer to obtain useful sheet ...

  3. Graphene - Wikipedia

    en.wikipedia.org/wiki/Graphene

    Graphene (/ ˈ ɡ r æ f iː n /) [1] is a carbon allotrope consisting of a single layer of atoms arranged in a honeycomb planar nanostructure. [2] [3] The name "graphene" is derived from "graphite" and the suffix -ene, indicating the presence of double bonds within the carbon structure.

  4. Electronic properties of graphene - Wikipedia

    en.wikipedia.org/wiki/Electronic_properties_of...

    Graphene is a semimetal whose conduction and valence bands meet at the Dirac points, which are six locations in momentum space, the vertices of its hexagonal Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K′. The sets give graphene a valley degeneracy of gv = 2.

  5. ‘Wonder material’ graphene makes huge step towards practical use

    en.wikipedia.org/wiki/Applications_of_nanotechnology

    Graphene batteries being tested in experimental electric cars have promised capacities 4 times greater than current batteries with the cost being 77% lower. [26] Additionally, graphene batteries provide stable life cycles of up to 250,000 cycles, [27] which would allow electric vehicles and long-term products a reliable energy source for decades.

  7. Two-dimensional semiconductor - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_semiconductor

    A two-dimensional semiconductor (also known as 2D semiconductor) is a type of natural semiconductor with thicknesses on the atomic scale. Geim and Novoselov et al. initiated the field in 2004 when they reported a new semiconducting material graphene, a flat monolayer of carbon atoms arranged in a 2D honeycomb lattice. [1]

  8. Graphene plasmonics - Wikipedia

    en.wikipedia.org/wiki/Graphene_plasmonics

    So far, the graphene plasmonic effects have been demonstrated for different applications ranging from light modulation [15] [16] to biological/chemical sensing. [17] [18] [19] High-speed photodetection at 10 Gbit/s based on graphene and 20-fold improvement on the detection efficiency through graphene/gold nanostructure were also reported. [20]

  9. Potential applications of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Potential_applications_of...

    Researchers from Rice University and State University of New York – Stony Brook have shown that the addition of low weight % of carbon nanotubes can lead to significant improvements in the mechanical properties of biodegradable polymeric nanocomposites for applications in tissue engineering including bone, [6] [7] [8] cartilage, [9] muscle [10] and nerve tissue.
